Definitions

  • the invention is directed to a wheel disc, in particular re-V-belt pulleys and a method for producing rotationally symmetrical bodies, such as wheels made of non-cutting deformable material, wherein a disc blank with a consistently thick wall is split on the outside edge, the gap area subsequently expanded and possibly compressed and is profiled below.
  • EU-Al 012648 shows a generic manufacturing process.
  • a multiple V-belt pulley is produced from a disk blank or a round blank in such a way that the disk blank is first split on the outside edge and then this split area is rolled out and profiled in several steps.
  • the rim wreaths created by the splitting are first compressed at least in some areas so that the multiple V-profile can then be rolled in.
  • the splitting in single-profiled disks is also known, for example, from GB-PS 1 024 282 or in the case of multi-profiled disks from the French utility model 82 09 541.
  • the known methods have in common that the disc blank must have a wall thickness that enables the splitting as a first process step. This means that a certain weight is already determined by the thickness of the disc blank, which for technical reasons cannot be undercut.
  • the object of the invention is to provide a solution with which a reduction in weight can be achieved in spite of these predetermined restrictions, wherein the wall thickness of the disc blanks required for splitting can be undercut from the start.
  • this object is achieved according to the invention in that the outer edge region of the disc blank provided for splitting is swaged up prior to splitting.
  • the invention provides that the outer edge region is compressed to a thickness which corresponds to at least twice the wall thickness of the disk blank.
  • the invention is not limited to the ratio between the wall thickness of the disk blank and the wall thickness of the upset area, but this ratio has proven to be very practical. Obviously this ratio is achieved that with a given wall thickness that allows splitting, the disk blank can be made half as strong, which leads to enormous weight savings. Depending on the field of application of the end product, these conditions can of course be chosen completely differently, in order to repeat this.
  • the upsetting of the outer edge region takes place in several stages.
  • the invention provides that the upset edge region is split off-center in such a way that the two wreaths created by the split have different wall thicknesses and the end profile is profiled in such a way that the hub part is arranged off-center.
  • the invention also provides a wheel disc, in particular a multiple V-belt pulley, which has been profiled from a disc blank by splitting and subsequent shaping.
  • Such adfusionn R art are for example known by the generic state.
  • the disadvantages, which consist in particular in the large material requirement, have already been mentioned above for the method. These disadvantages apply here in the same way.
  • the above-mentioned object is achieved according to the invention in that the outer edge-side profile region is formed from an area of greater wall thickness, initially created on the disc blank, by compression than the disc blank, the subsequent splitting of this thickened outer edge region and the subsequent profiling of this region .
  • the invention provides that the wall thickness of the flange formed by the blank is smaller than the material thickness required for splitting. It is of course essential for this wheel disk that the disk blank was present as a flat or profiled sheet metal disk as the starting product, i. H. not as a cast or drop-forged part.
  • the wheel disc is formed from a blank of light or non-ferrous metal.
  • 1 to 7 show individual cross sections of a wheel disc according to the invention after individual processing steps.
  • F ig. 1 shows a round blank or a disk blank 1, the wall thickness of which is denoted by "x" and, in the example shown, is to be of such a size that it is no longer possible to split in a conventional manner. This measure would be for steel sheet z. B. about 2.3mm, for other materials this dimension is of course different.
  • the disc blank is compressed on the outside edge.
  • This area is designated by 2 in FIG. 2.
  • the wall thickness of this area 2 on the outer edge is designated by "y”. In the example shown, it should correspond to twice the wall thickness "x”.
  • This edge is subsequently split, so that two rings 3 and 3 'are formed, the wall thickness of which in turn has the dimension "x".
  • FIGS. 4 to 7 now show further process steps, the rolling out of this edge region 2 and the A uspro- filleting in a profile shape 4 of FIG. 6, or a P ro- filform 5 to Fig. 7.
